The son of two Harlemites, Gene was raised in New Jersey. Gene attended Fairleigh Dickinson University where he earned his B.S. in Mechanical Engineering. A “Jersey Guy” at heart, Gene chose to stay in his home state where he now resides with his wife and children.

Prior to founding DIVERSANT, Gene was the National Practice Director for Infrastructure Services at Spherion Technology where he managed the provision of IT staffing and solutions for large clients nationwide. With an extensive background in the staffing and technology services industry, Gene now combines his business acumen with his desire to help others by developing transformative programs that promote diversity in the workforce and supply chain.

In his local community, Gene coaches minority youth about how they can get involved with technology and use it to advance their careers and lives. A member of Alpha Phi Alpha, the country’s first African-American fraternity, Gene is very active in many of their community service programs. Gene believes that each person should set his or her own destiny, and does what he can to help them on their path. “No one can stop you from reaching the stars,” he says. “It’s up to you. How badly do you want it?”
